Seoul, Dhu-AlHijjah 1, 1436, Sep 15, 2015, SPA -- North Korea said Tuesday it had restarted operations at its nuclear complex, dpa reported. A uranium enrichment plant and a 5-megawatt reactor at the Yongbyon complex had been readjusted as part of many "innovations," Yonhap News Agency reported, quoting North Korea's official KCNA news agency. South Korea's Defence Ministry said any such launch would be a "serious provocation, a military threat and a violation of UN resolutions," Yonhap reported. --SPA 12:17 LOCAL TIME 09:17 GMT www.spa.gov.sa/w
